CONNECTOR FOR BATTERIES.

Application filed January 26, 1920.

To all a ham it may concern Be it known that I, WILLIAM \Vonssnnn, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Connectors for Batteries, of which the following is a specification.

My invention relates to certain new and useful improvements in connectors for batteries, the peculiarities of which are hereinafter described and claimed.

The main object of my invention is to provide means for readily connecting abattery with various sizes of terminal tips of cables in common use; secondly to provide a simple, effective connector that can be cheaply manufactured; and thirdly to provide means for directly coupling up my connector with a cable tip.

Service stations for charging and recharging batteries for example, are called on to connect cable tips of various sizes with a battery, and the means I am about to describe facilitate such electrical connection, avoid delay and improve service. The usual cable tip is a tapered piece having a socket in the larger end into which the end of the cable is soldered. The smaller end has a recess that is interiorly threaded to match a bolt by which the tapered tip is drawn into close engagement with a matching block or other piece.

In the accompanying drawing on which like reference letters indicate corresponding parts, Figure 1 represents a side view of a binding post of a battery, and a cable tip coupled to said post by a connector exemplifying my improvements; Fig. 2 is a plan view of my clamping connector alone; Fig. 3, a detail of an interposed piece adapting said connector to a larger size of tip indicated by dotted lines; Fig. 4, an end view of said interposed piece; Fig. 5, a modified form of my connector; Fig. 6, a modified form of my adapter; Fig. 7 a male form of cable tip; and Fig. 8, an end view of my adapter shown in Fig. 6.

In Fig. 1 is shown a straight post binding post A forming part of a battery, B a leading wire to which is soldered or permanently fastened the usual or approved form of cable tip 0, having a tapered end with a recess D interiorly threaded, adapted to engage a screw-threaded stub E, forming one end of a body that is divided by a split into main and minor members F and F Specification of Letters Patent.

respectively, which are connected by a fiat ring portion G, forming an opening with preferably tapering sides adapted to engage and be clamped upon said binding post A by suitable means acting to dra t gether the members of said body; such as a bolt H threaded into the main member and loosely seated in the minor member so that by tightening the bolt the split will be dimmished in size and a clamping action brought upon said ring. The threaded recess in the main portion or body member F preferably does not pass all the way' through but is made as shown in Fig. 2 to The or a spot face on the outside of the minor member, and the bolt extends transversely across the split. The split is so arranged at one side with regard to the screw-threaded end E, that full strength is given to the threaded portion of the main member F. so that a firm engagement may be made with the cable tip C. The axis of the threaded portion E is substantially radial to the center of the ring G which simplifies the assembling of the cable tip, battery post and connector. Other tightening means than the bolt may be used.

When a larger size of tip as dotted in Fig. 3 is to be coupled to the binding post, I use an adapter consisting of a cylindrical piece having threads on the ends J and K, and a middle portion L, angular or otherwise adapted to be engaged by a wrench to turn said piece in engaging and disengaging it. The end J has a recess 7 interiorly threaded and of diameter matching the threaded stub E, Fig. 2, of the connector.

The other end K is of larger diameter according to the diameter of the female tip thus the end J can be screwed on the said connector and the end K can be screwed into the recess of the tip C; then the clamping ring can be engaged with the straight post of the battery.

A modified form is shown in Fig. 5, in which the screw stub of Fig. 2 is replaced by a socket or recess f in the main member F, which recess is interiorly threaded and adapted to be engaged by the male member K of the adapter shown in Fig. 3, or other suitable interposed piece, having on the other end the female threaded portion J that will therefore engage with a cable tip C,the tapering end of which tip is provided with a screw-threaded stub M of such diameter as to match the recess in the female portion of the adapter. Fig. 6 shows a modified form of the adapter in which the screw stub K on one end, can be engaged with a suitable threaded recess on either the socket connector wit-h the clamping ring, (Fig. 5) or with a female tip C; and has on the opposite end a recess-threaded end which is provided likewise with exterior threads Fl" that can be engaged by a female cable tip oi suitable or matching size. Thus this form of adapter has a screw stub on one end, and a female and male stub combined on the opposite end,-the two ends being separated by a hexagonal or other angular middle portion by which the adapter is rotated. Fig. 8 shows an end view of this double form of end J for the adapter shown in Fig. 6.

' By these means cable tips of various size and diameter, either male or female, can be readily coupled to my connector, thus facilitating assembling of various "forms and sizes of cable tips according to circumstances that may arise in every day service.

In both male and female connector shown in Figs. 2 and 5 the axis of the threaded portion is substantially radial from the center of the clamping ring so that the cable tips and wires are likewise radially connected. Any suitable material such as brass may be used for these electrical connecting means and said connector may be used with or without the adapter as may be required.

I claim:

1. A clamping connector of the class described comprising a body divided by a split into main and minor members,one

. larger than-the other said members being connected by a ring portion and the main member havmg screw threads at its end opposite the ring portion and having also a threaded socket located between the ring portion and the opposite end, and the minor member having a hole matching the threaded socket,and a stud bolt passing through said hole in the minor member and engaging said threaded socket to compress the split body.

2. The combination with a terminal post of a battery and a cablev tip soldered at one end to a cable and having threads at the other end,"of a clamp temporarily engaging said post at one end and having threads of different diameter from those of said cable tip,0-ne of the last two members having female threads and the other having male threads,and "an interposed piece having its ends threaded male and female and of different diameters and respectively matching threads of the clamp and cable tip.

3. An electrical connector comprising two pieces having non-matching threaded portions, and an interposed piece constituting an adapter and consisting of two exteriorly threaded ends of different diameter,-the

larger end having a socket interiorly threaded and of less diameter than the smaller of the exteriorly'threaded ends.

4. An electrical connector comprising a clamping ring having a body portion with a recess interiorly threaded, a cable tip having a screw-threaded stub at one end and soldered to a cable at the other end, and an interposed piece having a socket end with interior threads adapted to match said stub of the cable tip and having at the opposite end a screw-threaded stub adapted to match said reeess,the threaded portions on the interposed piece being of different diameters, substantially as described.

In testimony whereof I have aflixed my signature.

WILLIAM WOESSNER.
